Abstract

An innovative VLSI architecture for JPEG-LS compression algorithm is proposed, which implements real-time image compression either in near lossless mode or in lossless mode. The proposed architecture mainly includes four parallel pipelines, in which four pixels from four continuous lines could be processed simultaneously with a specific coding scan sequence, which ensures low complexity and real-time data processing. Our VLSI architecture is implemented on a Xilinx XC2VP30 FPGA. The experiment results show that our hardware system has the same results in image quality and compression rate as the standard JPEG-LS method and the processing speed of our system is four times more than that of traditional method.
